How does the function structure work in Go?

In Go, a function is defined using the 'func' keyword, followed by the function name, parameters, and return types.

Can you give me an example of a simple function?

Sure! Here's a simple function that adds two integers:

func add(a int, b int) int {
    return a + b
}

What are the different types of parameters I can use?

You can use various types like int, float64, string, and even custom types. Go also supports variadic functions.

What are variadic functions?

Variadic functions can accept a variable number of arguments. For example:

func sum(nums ...int) int {
    total := 0
    for _, num := range nums {
        total += num
    }
    return total
}
